[0002] HVAC pipelines have a very wide range of applications in the market; purification system supply and return air ducts, central air-conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust air ducts, mine gas drainage pipes, mine coated fabric air ducts, etc. The thickness and specifications of HVAC pipelines can be variable according to requirements. Usually, when connecting, both ends of the air duct are always externally connected to fittings (such as elbows, reducers). Among them, pipeline connectors are often required during the connection process of HVAC pipelines.

[0003] When the existing detachable and installable HVAC pipeline connectors are in use, most of them install two pipelines together through clamps. However, due to the weak pressure-bearing capacity of the pipeline connectors, the hollow pipelines are prone to deformation under external forces, resulting in leakage, which is not convenient for use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a building HVAC structure and an HVAC joint assembly to solve the problems in the prior art that the pressure-bearing capacity of the pipeline connectors is weak, the hollow pipelines are prone to deformation under external forces, resulting in leakage, and it is not convenient for use.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A building HVAC structure and an HVAC joint assembly, including a sleeve. A sealing ring is fixedly connected inside the sleeve. HVAC pipes are arranged inside the sleeve on both the upper and lower sides of the sealing ring. One adjacent end of each of the two groups of HVAC pipes abuts against the sealing ring. An installation and fixing mechanism is arranged on the side wall of the sleeve. The two groups of HVAC pipes and the sleeve are fixed through the installation and fixing mechanism. The installation and fixing mechanism includes a U-shaped frame and a lifting assembly. A U-shaped frame is fixedly connected to the left side wall of the sleeve. A moving block is slidably connected inside the U-shaped frame. Lifting assemblies are arranged at both the upper and lower ends of the moving block. A connecting block is arranged on the side of the lifting assembly away from the U-shaped frame. A fixed clamping assembly is arranged on the side wall of the connecting block. The fixed clamping assembly is used for clamping and fixing the HVAC pipe.

[0007] Preferably: A first threaded rod is rotatably connected to the left side wall of the sleeve. The left end of the first threaded rod penetrates through the moving block and the U-shaped frame. The first threaded rod is threadedly connected to the moving block and rotatably connected to the U-shaped frame.

[0008] Preferably, the fixed clamping assembly includes a fixed clamping plate and a movable clamping plate. The side wall of the connecting block is fixedly connected with the fixed clamping plate. One end of the fixed clamping plate is rotatably connected with the movable clamping plate, and the other end of the fixed clamping plate and the end of the movable clamping plate away from the fixed clamping plate are fixedly connected through a locking mechanism.

[0009] Preferably, a reserved groove is formed on the other end face of the fixed clamping plate, and a U-shaped groove is formed on the end face of the movable clamping plate away from the fixed clamping plate.

[0010] Preferably, the locking mechanism includes a rotating block. A bolt is fixedly connected to the side of the rotating block close to the movable clamping plate. The end of the bolt away from the rotating block penetrates through the U-shaped groove.

The threaded sleeve is internally threadedly connected with the second threaded rod, and the end of the second threaded rod away from the moving block penetrates through the connecting block and is rotatably connected thereto.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the synergistic action of the U-shaped frame, the first threaded rod, the moving block, the lifting assembly, the connecting block, the fixed clamping plate, the movable clamping plate and the locking mechanism, the first threaded rod is rotated to make the moving block move along the direction of the sleeve, so as to drive the arc surface on the fixed clamping plate to be in close contact with the outer wall of the HVAC pipe. Subsequently, the movable clamping plate and the fixed clamping plate are locked to each other by using the locking mechanism to ensure that the outer wall of the HVAC pipe is clamped and fixed, so that the HVAC pipe can be firmly fixed on the sleeve.

[0014] 2. By utilizing the synergistic action of the threaded sleeve and the second threaded rod, the connecting block is driven to move towards the U-shaped frame by rotating the second threaded rod. This action further pulls the HVAC pipe in the fixed clamping assembly towards the sealing ring, making the end of the HVAC pipe close to the sealing ring in close contact with the sealing ring. Such a design ensures good sealing performance of the connection between the HVAC pipes, solves the problems of weak pressure-bearing capacity of the pipe joints, easy deformation of the hollow pipes under external force resulting in leakage, and inconvenience in use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to Figures 1-5 As shown, the present utility model provides a building HVAC structure and an HVAC joint assembly, including a sleeve 1, a sealing ring 11 is fixedly connected inside the sleeve 1, HVAC pipes 2 are arranged inside the sleeve 1 on both the upper and lower sides of the sealing ring 11, and adjacent ends of the two groups of HVAC pipes 2 are in contact with the sealing ring 11. An installation and fixing mechanism 3 is arranged on the side wall of the sleeve 1, and the two groups of HVAC pipes 2 and the sleeve 1 are fixed through the installation and fixing mechanism 3; by arranging the installation and fixing mechanism 3 on the side wall of the sleeve 1, the HVAC pipes 2 on both sides of the fixed sleeve 1 can be fixed, and the sealing performance of the connection between the HVAC pipes 2 can be enhanced, thereby solving the problems that the pressure-bearing capacity of the pipe joint is weak, the hollow pipe is easily deformed by external forces and causes leakage, and it is not convenient to use.

[0023] In a further embodiment, referring to Figures 2-4, the installation and fixing mechanism 3 includes a U-shaped frame 31 and a lifting assembly 34. The left side wall of the sleeve 1 is fixedly connected to the U-shaped frame 31. A moving block 33 is slidably connected inside the U-shaped frame 31. Lifting assemblies 34 are arranged at both the upper and lower ends of the moving block 33. A connecting block 35 is arranged on the side of the lifting assembly 34 away from the U-shaped frame 31. A fixed clamping assembly 36 is arranged on the side wall of the connecting block 35. The fixed clamping assembly 36 is used to clamp and fix the HVAC pipe 2. The left side wall of the sleeve 1 is rotatably connected to a first threaded rod 32. The left end of the first threaded rod 32 penetrates through the moving block 33 and the U-shaped frame 31. The first threaded rod 32 is threadedly connected to the moving block 33 and rotatably connected to the U-shaped frame 31.

[0024] In this embodiment, by rotating the first threaded rod 32, the moving block 33 moves. The movement of the moving block 33 drives the lifting assembly 34 to move, and then drives the connecting block 35 to move, so that the fixed clamping assembly 36 approaches the HVAC pipe 2 and clamps and fixes it, ensuring that the HVAC pipe 2 is firmly fixed on the sleeve 1.

[0025] In a further embodiment, referring to Figures 4-5 , the fixed clamping assembly 36 includes a fixed clamping plate 361 and a movable clamping plate 362. The fixed clamping plate 361 is fixedly connected to the side wall of the connecting block 35. One end of the fixed clamping plate 361 is rotatably connected to the movable clamping plate 362. The other end of the fixed clamping plate 361 is fixedly connected to the end of the movable clamping plate 362 away from the fixed clamping plate 361 through a locking mechanism 4.

Subsequently, the rotating block 41 is operated to drive the bolt 42 to rotate so that it enters the U-shaped groove 3621. Next, by rotating the nut 43, it is moved along the specified direction until it contacts and fixes the movable clamping plate 362. This series of actions ensures that the HVAC pipe 2 is firmly clamped by the fixed clamping plate 361 and the movable clamping plate 362, realizing stable fixation.

[0027] In a further embodiment, referring to Figures 2-4, the lifting assembly 34 includes a threaded sleeve 341 and a second threaded rod 342. Threaded sleeves 341 are fixedly connected to both the upper and lower ends of the moving block 33. The second threaded rod 342 is threadedly connected inside the threaded sleeve 341. One end of the second threaded rod 342 away from the moving block 33 penetrates through the connecting block 35 and is rotatably connected thereto.

[0028] In this embodiment, by rotating the second threaded rod 342, the connecting block 35 is driven to move towards the U-shaped frame 31. This action further pulls the heating and ventilation pipe 2 in the fixed clamping assembly 36 towards the sealing ring 11, causing the end of the heating and ventilation pipe 2 close to the sealing ring 11 to be in close contact with the sealing ring 11. Such a design ensures good sealing performance for the connection between the heating and ventilation pipes 2, solving the problems of weak pressure-bearing capacity of the pipe joints, easy deformation of the hollow pipes under external forces resulting in leakage, and inconvenience in use.
